Geology and its relation to ground water, and history of ground-water development in the Wayne County
This resource is a metadata compilation that contains records for 14 investigative reports on geology, its relation to groundwater and the history of groundwater development in different areas and counties throughout Michigan. The metadata provides header features including title, description, author, originator, citation, distributor, and URL access for file downloads. This workbook was compiled by the Michigan Department of Environmental Quality, Office of Oil, Gas and Minerals and made available for distribution through the National Geothermal Data System.

In this paper the use of CAD software for the Visualisation of geothermal field features in three dimensions has been investigated. A 3D drawing of the Kawerau field has been developed. Drawing methods and technique are explained. The usefulness of the Vi
This paper summarizes an ongoing numerical modeling effort aimed at describing some of the thermodynamic conditions observed in vapor-dominated reservoirs, including the formation of a high temperature reservoir (HTR) beneath the "typical" reservoir. The primary results obtained in this study are as follows:
1) The liquid cutoffs are the most important characteristics of the relative permeability curves
2) The relative permeability parameters can be determined from field data in terms of the flowing enthalpy, and compared to theoretical curves (e.g., Corey and "X" curves)
3) The rise in flowing enthalpy can give information regarding the relative permeability curves providing parameters such as kH and Q are known (e.g., from injection and interference tests).
In two-phase flow through a porous material, the movement of each individual phase is retarded by the presence of the other; the degree of interference depending, among other things, on the volumetric proportion of the two phases. This phenomenon is expre
